SELF-LUBRICATING- DEVICE FOR J OURNAL BOXES."

To all whom it may concern Be it known that 1, Forums C. BUELL, acitizen of the United States, residing at St. Augustine, in the countyofSt. Johns and State of Florida, have invented certain new and usefulImprovementsin Self-Lubricating Devices for Journal-l3oxes, of which thefollowing is a specification, reference being This invention relates toan improved automatic or self-lubricatmg device for ournal boxes, .forrailway car axles and the i and combmation ofparts, as hereinafterv setlike.

The invention aims to provide a I self lubricating device, which willnot only renthe oil, and will render a saving in the amount of brass tobe used.

.The invention further aims to provide a lubricator, in which thelubricantis repeatedly employed, for lubricating the j ournaled ends of.the car and locomotive axles.

A further object of the invention is to afford constant revolublemembers, revoluble motion being imparted thereto, owing to the membersbeing in contactwith the journaled ends of the axle there being. meanson the revoluble members, acting to splash or agitate the lubricant, anddistribute it to the contact parts.

A further object of the invention is to provide spring tensioned guidebearings for the shaft of the revoluble member, in order to yieldincident, tolthe vibration of, the truck.

A further object of the invention is to provide guides for the guidebearings, and deflecting walls for returning the lubricant to the centerof the journal box, so as to be agitated by the means on. the revolublemember.

A further object of the i'nventionis to provide lubricant conductingchannels or grooves on the revoluble member, for conveying the lubricantto the guide bearings.

A further object of the invention "is to Specification of LettersPatent.

provide retaining means on the revoluble membeiyfor retaining thesplashing or agi-' tating means in substantially uniform locations. L

'. While the structure now illustrated, and

described is deemed preferable, in a reduction quired, and the. righttothese alterationsis claimed provided they ar warranted within .the scopeof what isclaimed The invention. comprises further features forth, shownin the. drawings and claimed.

Referring more especially the drawings ldesignates an axle and 2 denotesthe journal box, in which the end'of the'axle 3 is .journaled.

A. self-lubric atin device is disposed on the interior of the journalboxin the bottom thereof, and it comprises the curved orflat bottom plate iand the end guide plates 5 and6. The curved portions of the plates 5 and6 are provided with lateral flanges 7, to which the segmentalcurved'plate' i" is secured. Theflanges 7 extend inwardly toward eachother. The end flanges 5 and 6 are spaced, as shown, and

the vertical edges of the plates 5 and 6have lateral flanges 9. The endplates 5 and 6 are spaced in order to provide guides 9 for the guidebearings 10. The guide bearings have their side edges provided .withgrooves or channels 11, for the reception of the vertical flanged edgeparts of th end plates 5 and 6. Interposed between the guide bearings.and the upper end surfaces 'of the plate 4 are coil springslQ. Eachofthe coil springs is constructed from a single piece of steel or. brassspringwire of heavy Y P en d l 8, 191

gage, which is coiled, providing a small spring on the interior of alarger spring, the opposite ends of the inner spring being maintained inposition and against displacement by the devices as shown at 13.

Mounted in the guide bearings is a shaft 14. It is to be observed thatthe inner guide bearing 10 has a closed recess for one end of the shaft14-, thereby preventing inward movement of the shaft. The opening in theother guide bearing is open-ended, so that the shaft may pass throughthe same when arranging the shaft in position. A screw cap 15 isthreaded into the opening 16 of the outer guide bearing to prevent axialmovement of theshaft. It is to be noted that the wall of the journal boxis provided with an opening 18, for the reception of screw plugs 19.This opening 18 is in axial alinement with the shaft 14:, in order topermit the removal and insertion of the shaft in its guide bearings.

A revoluble lubricant distributing member 19 is provided, the borethrough this member 19 is lined with a brass sleeve 20, through whichthe shaft 14 extends. It is obvious that thiscsleeve rotates with therevoluble lubricant distributing member 19. The revoluble member 19 isprovided With annular channels 21, which are engaged by the centrifugalactuating chains 22. These chains are in the form of link or closedloops, and when the member 19 is at rest, these chains depend from themember and hang in the lubricant,vwhich is contained on the surface ofthe plate 4. It is obvious that the cylindrical surface of the member 19contacts with the end 3 of the axle. Therefore, when the axle is inmotion, revoluble movement will be imparted to the member 19. Thismovement of the member 19 will cause the chains 22 to swing out wardlyowing to the centrifugal action, and agitating the lubricant andsplashing the same upon all cont-acting parts, and it is obvious thatthe lubricant returns to the surface of the plate 1, when the movingparts are at rest.

It is to be observed that the plates 5 and 6 have on their upper edgeportions inwardly extending lateral flanges 23, which together with theflanges 9 act to return the lubricant to the surface of the plate 4;. Inother words, the flanges 9 and 23 act as lubricant guards or deflectors.

The bottoms of the annular channels 21 are provided with flat portions,which not only act as agitating means for the lubricant,

should the level of the same reach the bottoms of the channels, but alsoact as means to prevent the bottoms of the channels from rotating withrelation to the splashing chains, without imparting a swinging orcentrifugal movement to the chains. How- 'use of all waste iseliminated.

like construction.

ever, it is obvious that there will be some slipping action between thechains and the bottoms of the channels, but not enough to foil thepurpose of the splashing chains. It is obvious that the faster therevoluble member rotates, the more secure will the chains adhere to thebottoms of the channels, therefore the actions will be more efficient.The bottoms of the channels 21 of the member 19 are provided withopenings 25, which extend entirely through brass sleeve of the annularmember 19, so that certain of the lubricant will feed to and contactwith the shaft 14:.

The outer circun'iference of the revoluble member 19 intermediate theadjacent channels, and between the channels and the ends of the member19 are lubricant feeding grooves 26, which are obliquely disposed andhave their bottoms almost on a level with the bottoms of the channels,and act to feed the lubricant toward the ends of the revoluble member orroller 19 to the guide bearings.

The intermediate lubricant feeding grooves 26 will act to conveylubricant from one channel to another.

It is to be noted that the wall of the journal box has secured theretoas at 27 a deflector plate 28 which is inclined at an acute angle to thewall of the journal box and constitutes means to deflect the lubricantback to the bottom of the journal box,

,tom wall of the journal box has a draining opening 31, which isthreaded for the reception of a plug '32. This plug may be removed fordraining the journal box of the lubricant.

By the employment of this invention, the Further in all mechanisms,where revoluble elements or parts are provided, this lubricator may beinstalled, and maybe constructed to fit any style or construction ofjournal box, having either fiat or round bottoms or any If desired theparts 4, 5, 6 and 7 of the frame may be constructed or cast in onepiece. Also a frame and lubricator constructed substantially as embodiedherein may especially be employed for use in connection with second-handjournal boxes, that is those now in use. In this case, however, theframe may be fastened to the j ournal. box in'any conventional manner.
